If you go and check out Susan's Card Sketch a Day Blog you'll see these:
The tree card features some printables by Marieke Vermeulen Design, I am a huge fan of her stuff and it's a great way to stretch your crafting dollars. Speaking of stretching, another great money saver is to use your stash! The green and orange card is made with Scenic Route circa 2005.
Now go check out Susan's site - it's awesome. She even does calls so your cards can be featured too.
